Failing to access data due to two migrations running at the same time

Marco Vici April 11, 2023


As per the title, I have some errors in the log files generated when I try to run a migration from Server to Cloud, using the Migration Assistant.

It seems this is a known problem in Windows environment. Has this problem been resolved?


Thank you,

Hi @Marco Vici ,


Welcome to Atlassian Community!

As per the logs, Due to some time request error in the JCMA this error happened.

Anyway, I think it will be the best to create migration support issue directly to Atlassian to help you with this.

Please create a support Migration ticket they will help you.
